Motion Detector

[alexyak]

@plumcraft strange, I’ve RPI 3 as well and I don’t see this problem … This may be related to which monitor/TV your RPI is connected.

I assume too that the behaviour is different between TV’s. On my LG the screen turns blue with a big message of lost signal on HDMI after 10 seconds after the screen turns off. Not so nice - but then again, nobody should be in the room anyway…? ;-)

I installed it… it turns off the monitor but won’t turn it back on… suggestions?

[cowboysdude]

@plumcraft Yeah there doesn’t seem to be an answer for the blank screen issue…

[alexyak]

I am sorry to hear about your issues. Trying to think of the best way to troubleshoot that. The module doesn’t do anything fancy. It just executes these in the node_helper to switch on/of the output on HDMI:

Switch off:

/opt/vc/bin/tvservice -o

Switch-on:

/opt/vc/bin/tvservice --preferred && sudo chvt 6 && sudo chvt 7

As a first step, could you please try to execute these commands in the ssh terminal?

Hi alexyak

I try it with the commands an it works, it switch off and on.

[alexyak]

Ok, the next step let’s check whether the off state is detected correctly. After you switched off the monitor with the first command try to execute this in the ssh term:

/opt/vc/bin/tvservice -s

and let me know which output you see.

output is:
state 0x120002 [TV is off]

@trividar @cowboysdude paviro is also using the same code lines in his pir sensor module and a user had similar issues, maybe his solution also work for you
